global navigation satellite systems

global navigation satellite systems As we know global navigation satellite systems (GNSS) play a key role in positioning vehicles on an accurate map. It is important to protect Global Navigation Satellite System (GNSS) from spoofing and injection of fake messages as the most dangerous attacks (i.e., most likely or most severe). Therefore, manipulating GNSS data could provoke erratic and inaccurate maneuvers, which could endanger passengers. In this task, I am looking for different techniques that are proposed to authenticate GPS signals for Intelligent Transportation System (ITS). The technique can have cryptographic authentication or any other techniques against spoofing attacks. The proposal shall sufficiently detailed to facilitate near-term implementation of GPS signals. I am looking for ways to secure GPS signals in Intelligent transportation system using new sources 2016 (papers or patents ) summaries the problem and provide the technical solution with citation The paper attached will help you to know what I am looking for. Do not use old sources I need current ones Attachments area The biggest threat to automated vehicles is spoofing, which is essentially the sending of false messages that may be relayed on the network. To effectively address the issue of spoofing, automated vehicles need to be fitted with authentication systems that can detect any attack. By using multiple authentication systems, it can be possible to authenticate the source of the GNSS signals and confirm if they are valid or not. Just like the two step verification method that is popular in email authentication, it can be possible to come up with a similar system that will ensure only the valid GNSS signals are fed into the automated vehicle. ?
